THZ-100 THERMOSTAT
Welcome To Your THZ-100 Thermostat
Congratulations on your purchase of this THZ-100 Thermostat from
URC. Enjoy the full functionality of a stand-alone thermostat
coupled with the ability, when used with a Total Control system, to
be controlled from any user interface in the system. No more
shivering under the covers, dreading to dare the inevitable cold on
the way to the shower; grab the remote and make it nice and toasty,
before removing the blanket!
Some of the advanced, and unique features found on the THZ-100
are:
Optional Wired Sensor
Easily add an additional sensor to the thermostat by purchasing the
optional wired sensor. With the ability to temperature average
between the sensor and the main unit, or simply take the place of
the main unit’s on-board sensor, you can increase both efficiency
and accuracy of temperature readings.
Intelligent Comfort Recovery
Every good thermostat has the ability to set heating and cooling
schedules, but if you wake up at 7:30am, setting your heat to come
on at 7:30am means waking up to an uncomfortable home while
your system reaches your desired temperature. With Intelligent
Comfort Recovery, the THZ-100 monitors the current temperature
of your home and determines the amount of time it will take to
reach your desired temperature at the desired time. Then, it slowly
and more efficiently heats or cools to the new set point.
Security Code
Perfect for most commercial uses, and even for some homes where
people have the need to ensure that only authorized people should
have access to the THZ-100. Easily program your new thermostat
with a 4-digit security code to make sure that only people with the
code can access the thermostat.
Total Control Peripheral
Perhaps the best benefit is the THZ-100’s complete integration into a
Total Control home system. When used with URC’s Total Control
system, the thermostat control can be accessed from any of the
system’s interfaces (dependent upon the system programmer). With
the ability to control all of the THZ-100s in the home, it is also easy
to incorporate heat/cool set points into various Automation
Activities. Although the possibilities are endless, imagine a
Goodnight button that would turn off your theater, turn off all the
lights and bring the THZ-100 to the chosen set point!

Installing Your THZ-100 Thermostat
Adding an optional wired sensor can be a benefit if the thermostat
location is not the optimal location for temperature measurement,
or if temperature averaging is desired.
• A wired sensor can be connected to the S+ and S- terminals
on the back of the unit
• This can be added to any of the wiring options detailed in the
next pages
For optimum performance, mount the THZ-100 thermostat and/or
remote sensor
• In an open living area where there is good air circulation
• On an inside wall
• Away from outside doors or windows
• At a height about 5 feet from the floor
Avoid installing the THZ-100 thermostat and/or remote sensor
• In direct sunlight
• Above radiators or air vents
• Near fans or portable heating units
• Near lamps or other incandescent lighting
• Near other heat generating electric appliances such as
televisions, audio video equipment, refrigerators, freezers,
ovens, cooktops, etc.
Other precautions when installing the THZ-100 thermostat and/or
remote sensor
• Make sure the cutout for the HVAC wiring is no larger than
needed to make proper connections to the thermostat
• If there is a large air gap in the cutout for the HVAC wiring,
insulate around the wire and close off the air gap
• Make sure the air vents in the THZ-100 thermostat and/or
remote sensor are clear of dirt, dust, or any construction
material

Operation For Your THZ-100 Thermostat
Your THZ-100 thermostat has been programmed by the MRX
Advanced Network System Controller system with your custom
HVAC schedule of heat and cool set points for the selected time
periods for each day of the week. In addition, the thermostat has
been programmed by the MRX Advanced Network System
Controller for the type of HVAC equipment, conventional or heat
pump, the number of auxiliary heat and/or cool stages, any remote
sensors, and any pass code lockout code if desired.
Thermostat Display Information
Your THZ-100 thermostat features a color backlit LCD display with
all the information you need for easy operation. The top left of the
screen has the fan mode information while the top right of the
screen has the current system mode such as Heat or Cool.
The center of the screen displays the current temperature with
different backgrounds dependant upon whether the thermostat is in
Heating, Cooling or Idle mode. The small letter F or C at the lower
right of the current temperature indicates the temperature scale.
Directly above the current temperature is the name of the program
mode that is currently running: Morning, Day, Evening, Night,
Vacation, Override, Hold, or Hold to <time>. When the system is
OFF there is no text in this area.
Directly below the current temperature is information on the
current comfort range and the set points. This area is also used for
notifications such as Check Wireless, Check Network, or Check
Filter which alternates on screen with the set point information.

display to time out while the current and desired override
temperatures are displayed.
If you decide to cancel the operation, press the key below the
Cancel key label in the smart-key label at the bottom left of the
display.
This places the thermostat in the Override mode. While in this
mode, the thermostat holds your new temperature selection until
the next regularly scheduled time period in your pre-programmed
HVAC schedule.

Auxiliary Heat
Auxiliary heat consists of additional stages of conventional gas, or
electric heat, capacity included with most heat pump systems. The
auxiliary heat stages are automatically selected by the system when
the outside temperature is too cold for the heat pump to heat your
home effectively. The staging of the auxiliary heat is based on the
information selected in the MRX Advanced Network System
Controller setup of your thermostat.

selected by the user from the Options menu as described below
when additional heat capacity is desired. Emergency heat reduces
the energy efficiency of the heat pump system.When in emergency
heat, the display indicates this state in the upper right of the display.
Intelligent Comfort Recovery
When there are significant set point differences between
programmed set points of different program time periods your THZ-
100 anticipates the change in advance and begins to ramp the
current set point to the next programmed set point to give you a
smooth comfort transition. During this comfort recovery period the
thermostat indicates Comfort in place of Heat, Cool, or Idle in the
upper right of the display window. In addition, the display
background changes to indicate whether the system is heating or
cooling during this transition.
